Cost Segregation for

Commercial Real Estate

Cost Segregation is not a tax credit, rather it is a tax mitigation strategy that accelerates the depreciation of commercial real estate assets.

An engineering-based cost segregation study can significantly impact your cash flow in the near term by front loading the depreciation of your assets–freeing up cash and allowing you to take advantage of the time value of money.

WHAT IS COST SEGREGATION?

Accelerated Depreciation…

When you buy, build, or renovate real estate, the IRS normally makes you deduct the cost slowly — over 39 years for commercial property or 27.5 years for residential rentals. Cost segregation speeds that up. It’s an engineering-based study that identifies the parts of your building that legally qualify for much faster depreciation, moving them into 5-, 7-, and 15-year categories so you can deduct them now instead of over decades.

The timing couldn’t be better. With 100% bonus depreciation restored and made permanent for property placed in service after January 19, 2025, those reclassified assets can often be written off entirely in year one — turning a routine real estate purchase into a major near-term tax savings and a real boost to cash flow.

A Quick Example

An investor buys a commercial building for $3.5 million, of which $2.5 million is building basis (the rest is land). A cost segregation study identifies 28% — about $700,000 — as 5-, 7-, and 15-year property eligible for 100% bonus depreciation. That’s a $700,000 first-year deduction instead of roughly $64,000 under the standard 39-year schedule. For an owner in a 37% bracket, that’s on the order of $250,000 in first-year tax savings — against a study that typically costs a small fraction of that.

How Cost Segregation Works

 

A building isn’t really one asset — it’s hundreds. The walls and foundation genuinely last decades, but the carpeting, specialty electrical, decorative millwork, dedicated equipment, parking lot, and landscaping don’t. Standard tax depreciation lumps almost all of it into one long 39- or 27.5-year life. A cost segregation study separates those components and assigns each the shorter recovery period the tax law actually allows:

  • 5-year property — items like carpeting, certain fixtures, decorative finishes, and equipment-related wiring.
  • 7-year property — certain furnishings and equipment.
  • 15-year land improvements — parking lots, sidewalks, curbing, landscaping, and site lighting.
  • 39- or 27.5-year property — the building structure itself (what’s left).

Why it’s worth so much right now

Anything reclassified into a 5-, 7-, or 15-year life qualifies for bonus depreciation — and bonus depreciation is back at 100%. That means the portion of your building the study moves into those shorter categories can typically be deducted in the first year, rather than a sliver at a time. A typical study reclassifies 20% to 40% of a building’s cost into these faster categories.

The benefit is the time value of money: a deduction today is worth far more than the same deduction spread over 39 years. You’re not creating deductions out of thin air — you’re pulling them forward, deferring tax, and freeing up cash you can reinvest now.

Who it’s for

Cost segregation applies to a wide range of real estate — offices, retail, industrial, warehouses, medical, multifamily, and short-term rentals — whether you purchased, constructed, renovated, or expanded it. It only applies to the building and improvements, not the land (land can’t be depreciated). As a rule of thumb, the strategy tends to pay off well on buildings with a cost basis of roughly $500,000 or more, though strong-income properties can benefit at lower levels.

The Cost Segregation Process

1. Feasibility Check

We look at the property type, cost basis, placed-in-service date, and your tax situation, and estimate the likely benefit before you spend anything. If a study won’t pay for itself, we’ll tell you.

2. Data Gathering

We collect the closing documents, construction costs or purchase price allocation, blueprints or property records, and any renovation details.

3. The Engineering Study

Specialists analyze the property and its components, classify each into the correct recovery period, and value them using accepted, IRS-recognized methods — documented in a detailed report.

4. Delivery

The results flow into your depreciation schedule. The depreciation increases the expense on your P&L resulting in lower taxable income. We coordinate directly with your CPA so it’s applied correctly.

Already own the Property?

You don’t have to amend past returns. For real estate placed in service in a prior year, a look-back study lets you claim all the depreciation you could have taken — in one catch-up deduction in the current year — by filing an accounting-method change (Form 3115) with a Section 481(a) adjustment. It’s one of the most powerful and underused features of the strategy.

What to weigh before you do it

Cost segregation is powerful, but it’s a planning decision, not a free lunch — and part of our job is making sure it actually fits:

Depreciation recapture.

Accelerated deductions can come back as income when you sell the property. If you’re planning to sell soon, the math changes, though strategies like a 1031 exchange can help.

How you’ll use the deductions.

Real estate losses are subject to passive-activity rules — your ability to use them against other income depends on your situation A big deduction is only worth it if you can actually use it.

State conformity.

Not every state follows federal bonus depreciation, so the federal and state benefits can differ. Consult with your CPA to determine your state’s tax treatment.

Run through this quick self-check to see if a Cost Seg study is right for your situation:

– Do you own — or are you buying, building, or renovating — commercial or residential rental real estate?
– Is the building’s cost basis meaningful (roughly $500,000+)?
– Was it placed in service recently, or in a prior year? (Either works — prior years qualify for a catch-up look-back study.)
– Do you have taxable income — or real-estate-professional status — that allows you to utilize the deductions?

If you answered “yes” to most of these, a cost segregation study is very likely worth a look — often worth many times its cost in the first year alone.
